我不知道为什么这里会出现这个错误。我使用一个名为 ssh shell 的 mac 软件它可以连接到我的服务器。我很确定密码是正确的。

你的命令行并没有按照你想象的那样做。

ssh -v admin@myserver -P 6000

• -v 启用一些调试信息
• admin@myserver 提供远程用户和远程主机
• -P 6000 确实不尝试连接到端口 6000

您可能想要的命令是:

ssh -v admin@myserver -p 6000

然而，事实证明-P是一个undocumented argument ssh 接受。

这留下了一个下落不明的参数6000。 ssh 假定这是您要在远程服务器上运行的命令。它不存在，这会导致显示错误:

sh: 6000: command not found
